To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Power and Value !!!! A great buy from the world's best retailers. ( As usual ) Never any problems with purchasing from Amazon. I joined "Prime " and it's been absolutely super. Anyway, these little beauties have one characteristic..... they are there when you need them !!! Big charge at hardly any (charge) cost .
